BioMed X and the Universitätsmedizin Mannheim announced today the publication of two manuscripts in the field of cancer immunology in the journal Science Advances. The work is based on a collaboration bet- ween both institutions and researchers at the German Cancer Research Center (DKFZ), the Heidelberg Uni- versity, and the Helmholtz Institute for Translational Oncology (HI-TRON).

Scientists from the German Cancer Research Center (DKFZ) and ShanghaiTech University have developed an innovative method for growing brain tumors of individual patients in the laboratory that mimic the original structure and the molecular property of the parental tumor as closely as possible. Drug tests in this model were found to correlate very well with actual patient responses, making it a valuable method for investigating therapies.

Researchers at Heidelberg University Hospital (UKHD), the German Cancer Research Center (DKFZ) and at the National Center for Tumor Diseases (NCT) Heidelberg have demonstrated for the first time that there is a link between the development of colorectal cancer in individuals with Lynch syndrome and the composition of immune cells in the colorectal mucosa.

Mitochondria are the power plants of cells, and they contain their own genetic material and RNA molecules. Scientists from the German Cancer Research Center (DKFZ) have now discovered that certain modifications in mitochondrial RNA boost the invasive spread of cancer cells by supporting protein synthesis in mitochondria.

Cancer cells often grow in environments that are low in nutrients, and they cope with this challenge by switching their metabolism to using proteins as alternative "food". Building on genetic screens, an international team of scientists could identify the protein LYSET as part of a pathway that allows cancer cells to make this switch. Their findings are now published in the journal Science.

Treatment resistance is a central problem in the treatment of cancer. Bone and soft tissue tumors – known as sarcomas – in adolescents and young adults often stop responding to treatment too. This is because cancer cells develop a large number of new characteristics as the disease progresses and often become resistant to drugs that were originally effective.

How well do the algorithms used in the AI-supported analysis of medical images perform their tasks? This depends to a large extent on the metrics used to evaluate their performance. An international consortium led by scientists from the German Cancer Research Center and the National Center for Tumor Diseases has compiled the knowledge available worldwide on the specific strengths, weaknesses and limitations of the various validation metrics.

Glycolysis is an important sugar degradation pathway that cancer cells in particular depend on. Scientists at the German Cancer Research Center (DKFZ) have now shown that liver cancer cells in mice and humans depend on a key enzyme of glycolysis, Aldolase A. When it is switched off, glycolysis reverses from an energy-producing to an energy-consuming process.

Depending on whether the cell nucleus of an epithelial cell is located on the outer or inner side of the tissue, the genome is more or less acetylated - genes can therefore be translated easier or harder. Scientists from the German Cancer Research Center (DKFZ) have demonstrated this for the first time in the development of the Drosophila wing.

Scientists from the German Cancer Research Center (DKFZ) and the European Bioinformatics Institute EMBL-EBI, Hinxton, UK, are using the Danish health registers to predict individual risks for 20 different types of cancer with a high degree of accuracy. The prediction model can also be transferred to other healthcare systems.

Many people are infected with the Epstein-Barr virus (EBV), and most are unaware of it. However, EBV can sometimes cause cancer, and this pathogen also appears to play an important role in multiple sclerosis and other autoimmune diseases. Researchers have discovered that EBV increases the ability of infected immune cells to migrate. In this way, the pathogen promotes its spread in the body – a discovery that may have therapeutic implications.

Current diagnostic methods do not always reliably distinguish between chronic inflammation of the pancreas and pancreatic cancer. About one third of all diagnoses are inconclusive. Scientists from the German Cancer Research (DKFZ) and from Heidelberg University Hospital (UKHD) therefore searched for molecular markers that could specify this diagnosis.

Computer scientist Annika Reinke from the German Cancer Research Center (DKFZ) has been awarded the Hector Foundation Prize 2025, endowed with €10,000, for her outstanding work in the field of AI-supported medical image analysis. She received the award for the project Metrics Reloaded, which can significantly improve the quality and reliability of AI-supported image analysis.

Scientists from the German Cancer Research Center (DKFZ) and the Cambridge Stem Cell Institute have developed an AI system that recognizes and characterizes white and red blood cells in microscopic images of blood samples. The algorithm can help physicians diagnose blood disorders and is available as an open source method for research purposes.

Mutations of the tumor suppressor p53 not only have a growth-promoting effect on the cancer cells themselves, but also influence the cells in the tumor's microenvironment. Scientists at the Weizmann Institute in Israel and at the German Cancer Research Center (DKFZ) have now shown that p53-mutated mouse breast cancer cells reprogram fat cells.

In mice, inflammation in early to mid-life leads to a permanent decline in functional blood stem cells, according to a recent publication by scientists from the German Cancer Research Center (DKFZ) and the Stem Cell Institute HI-STEM*. The ability of the blood stem cells to regenerate was suppressed for at least one year after challenge with inflammation.

During infections, the hematopoietic system switches from normal to emergency mode. This improves the defense against the pathogens. Scientists at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have now found an epigenetic switch in blood stem cells and progenitor cells of mice that can trigger the switch from one mode to the other.

Scientists at the German Cancer Research Center (DKFZ) have shown in an international eye-tracking study that dermatologists not only improve their diagnostic accuracy by using explainable artificial intelligence, but also show significantly less fatigue when assessing challenging cases. The researchers were able to demonstrate this by measuring a reduction in cognitive stress indicators.

Do BMMFs, the novel infectious agents found in dairy products and bovine sera, play a role in the development of colorectal cancer? Scientists led by Harald zur Hausen detected the pathogens in colorectal cancer patients in close proximity to tumors. The researchers show that the BMMFs trigger local chronic inflammation, which can cause mutations via activated oxygen molecules and thus promote cancer development in the long term.

Colorectal cancer screening programs are currently underutilized in Germany. This also applies to testing for blood in the stool. The immunological stool tests can detect tiny amounts of blood in the stool. Scientists at the German Cancer Research Center (DKFZ) have investigated whether smartphone-based testing could be a meaningful alternative or supplement to traditional laboratory tests.

Screening trials for the early detection of rare diseases often fail due to insufficient predictive power of the results. For the rare HPV-related cancer of the pharynx, scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) now relied on the combined detection of antibodies against two different viral proteins in a proof-of concept trial.

Blood-based biomarkers allow the early prediction of Alzheimer's risks

Most dementia diseases develop insidiously and are only detected at an advanced stage. Researchers at the University of Heidelberg and the German Cancer Research Center (DKFZ) have now identified the glial fibre acidic protein (GFAP) in the blood as a promising biomarker that can be used to determine an increased risk of developing Alzheimer's disease up to 17 years before diagnosis.

Inflammatory fatty liver disease (NASH, non alcoholic steatohepatitis ) and the resulting liver cancer are driven by autoaggressive T cells. Scientists from the German Cancer Research Center (DKFZ) now show what ist behind this destructive behavior. In both mice and humans with NASH, they found increased numbers of activated B cells in the gastrointestinal tract.

Focusing on gut microbiome for CAR T-cell therapy

Cancer immunotherapies use the body's own defences to fight tumour cells. An international consortium of researchers from Germany and the USA led by the DKFZ in Heidelberg has demonstrated that the effectiveness of CAR T-cell therapies greatly depends on the composition of the gut microbiome. The researchers have also developed a model for predicting the long-term response to the treatment.

Scientists at the German Cancer Research Center (DKFZ), together with doctors from the Urological Clinic of the Mannheim University Hospital, have developed and successfully tested a chatbot based on artificial intelligence. "UroBot" was able to answer questions from the urology specialist examination with a high degree of accuracy, surpassing both other language models and the accuracy of experienced urologists.
